Parity of indices is the same as parity of values, i.e., a(n) = n (mod 2). Even terms are of the form a(2n) = -4*b(n), b=(0, 1, 99, 51638, 93513322, 446966147147, ...).
Motivated by the fact that A024282(n) is divisible by 2^(n-1). One might also consider A024282(n)/4^floor(n/2)*(-1)^(n+1) = (0, 1, 2, 31, 198, 7577, 103276, 7672397, 187026644, ...)
